Time-domain array factor for UWB antenna array

A cross-correlation formulation for the computation of time-domain array factor for ultra-wideband (UWB) antenna arrays is presented. In addition, a dual band UWB waveform is proposed for high directivity and high-resolution radar imaging. The dual band UWB waveform is based on a frequency truncated, Gaussian modulated, higher-order sinusoidal UWB pulse.
